Avago joins CFP MSA as specs for 40 and 100Gbps transceivers updated

Avago Technologies, Finisar Corp, Opnext, Inc and Sumitomo Electric Industries Ltd (SEI) have announced that Revision 1.4 of the CFP Multi-Source Agreement (MSA) hardware and firmware specification documents is now available on the CFP MSA.

In addition, the three firms Finisar, Opnext and SEI, which founded the CFP MSA and first announced it in March 2009, have welcomed Avago Technologies as a new member. Other manufacturer companies interested in joining the CFP MSA are encouraged to contact an existing MSA representative.

The CFP MSA’s aim is to define a hot-pluggable optical transceiver form factor to enable 40Gbps and 100Gbps applications, including next-generation high-speed Ethernet (40GbE and 100GbE). Pluggable CFP transceivers will support the ultra-high-bandwidth requirements of data communications and telecommunications networks that form the backbone of the internet.

Industry analysts forecast that, driven by high-quality video services like video-on-demand (VOD) and internet protocol television (IPTV) as well as the availability of high-speed and high-capacity access networks such as FTTx and WiFi, IP traffic volume is expected to nearly double every two years through 2013, potentially resulting in core network bandwidth shortages.

To prevent this, carriers and service providers are already planning the deployment of next-generation high-speed network protocols. The Institute of Electrical and Electronics Engineers (IEEE) has recently standardized 40 Gigabit and 100 Gigabit Ethernet under the P802.3ba Task Force and is currently working to add new features to 40 Gigabit Ethernet in the P802.3bg Task Force. In addition to the existing 40Gbps telecom standards, both the OIF (Optical Internetworking Forum) and the ITU-T (the International Telecommunications Union’s Telecommunication Standardization Sector) are working on standardizing SDH/OTN telecom interfaces for long-haul transmission of 100 Gigabit Ethernet.

Pluggable transceiver modules compliant to the CFP MSA will be used on these 40Gbps and 100Gbps interfaces. The CFP MSA is defining the specifications required to support multiple applications using the same form factor. These applications include various protocols (such as 40GbE, 100GbE, OC-768/STM-256, OTU3), media types (multi-mode and single-mode fiber optics) and link distances. The CFP MSA uses numerous innovative features like advanced thermal management, electromagnetic interference (EMI) management and enhanced electrical signal integrity design to define the transceiver mechanical form factor, the optical connector, the 10x10Gbps electrical connector with its pin assignments, the MDIO-based transceiver management interface and the hardware required on the system host board.
